The role of CDN (Content Delivery Network) in cloud computing is to improve the performance, scalability, and availability of web-based applications and services. CDN is a distributed network of servers strategically placed in various locations around the world.
When a user requests content from a website or application, the CDN identifies the user's location and serves the content from the nearest server in its network. This reduces the latency and improves the overall user experience by delivering the content quickly.
CDNs also help in handling high traffic loads by distributing the load across multiple servers. This ensures that the website or application remains responsive and available even during peak usage periods.
Furthermore, CDNs also provide additional security benefits. By caching and delivering content from their servers, CDNs can help protect against Distributed Denial of Service (DDoS) attacks by absorbing and mitigating the traffic before it reaches the origin server.
In summary, CDNs play a crucial role in cloud computing by enhancing the performance, scalability, availability, and security of web-based applications and services. They optimize content delivery, reduce latency, handle high traffic loads, and provide additional layers of protection against cyber threats.
